That 100 button for digital cable or satellite .

Conventional TV tuners are incapable of handling digital signals. The
higher numbers are for analog systems with more bandwidth. The state of
technology makes it impractical for cable operators to expand the analog
plant. Instead they place the added channels on a digital tier and force
customers to pay more for the service and a digital decoder.

So the +100 button is of no use in most cases unless you want to receive OTA
UHF stations with the tuner set for CATV. For channels 14-44, add 51 to get
the cable channel number, for 45 and up, add 56.
